Application filed September 4, 1.891. Serial No. 404,768. (Model.)

To @ZZ whom t may concern:

Be it `known that we, FRANK M. BEARD and FRANK P. SHEPARD, citizens of the United States, residing at Guthrie, in the county of Logan and Territory of Oklahoma, have invented a new and useful Permutation-Padlock, of which the following is a specification.

Our invention relates to permutation-padlocks; and it has for its object to provide a device of this character which will be simple in construction, strong and durable, and yet a padlock which is so constructed that the parts thereof cannot be unlocked unless the combination is known, by means of which the various parts may be thrown into alignment in their unlocked position, andrat the same time to provide a lock which may be operated by an almost indefinite numberof combinations, yet being provided with but few parts, which render the same less liable to become broken or out of order and unfit for use, while effecting the objects for which permutation-padlocks are constructed; and with these objects in view the invention consists in a pivoted hook controlled and operated in connection with the hasp of an ordinary padlock by specially constructedl and arranged tumblers and locking devices hereinafter more fully described, illustrated in the accompanying drawings, and specifically pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a perspective view of a permutation-padlock constructed in accordance with our invention. Fig. 2 is a front elevation of the lock, the front plate and dial being removed to expose the interior parts thereof in their locked position. Fig. 3 is a similar view showing the various parts in alignment and in their unlocked position. Fig. 4is avertical sectional view of the lock. Fig. 5 is a similar View illustrating the manner of changing the combination. Figs. 6 and 7 are detail views of the lock-casing and inclosing cap, respectively. Fig. 8 is a perspective view of the pivoted hook and the tumblers one above the other in their correct positions for assembling. Fig. 9 is a detail in perspective of the slotted locking-pawl.

Referring to the accompanying drawings, 1 represents the back plate or main casting of the lock, having the ordinary encircling flange 2, within which is inclosed the various parts of the lock, and is further provided with the central perforation 3, which is designed to accommodate the portions of the locking device to be described, and the periphery of which perforation being itself provided with the guide and retaining notch or recess 4. The said casing is inclosed by the usual cap `5, which is provided with a registering and corresponding perforation 6 and an aligning guide and retaining-notch '7, which lies directly over and in line with the corresponding guide and retaining-notch 4 in the main casting comprising the lock-casing.

Pivotally secured to the upper outer end of the casing 1 is the ordinary link or hasp 8, which is provided with the ordinary lookingshoulder 9, that is adapted to be thrown within the opening 10, located in the opposite side of said casing and designed for the reception of said hasp and be locked within the casing in the manner to be hereinafter described.

' A revolving operating-plate 11, provided with a notched peiiphery'12, is designed to work upon the outside of the back plate 1 and is provided with an inwardly-extending annular flange 13, that is designed to register with thesides of the central perforation 3, and, fitting snugly therein, is designed to form a bearing for said revolving plate, which is further provided with a central inwardly-extending hollow neck or collar 14, which extends through the barrel of the casing and forms a pivot or operating stud, upon which are mounted portions of the locking device. Said I annular fiange 13 is provided with a notch or opening 15, which as said plate is revolved and operated is designed to be thrown into alignment with the notches 4 and 7, respectively, of the back and front plates comprising the lock-casing, and said annular flange is inwardly beveled, as shown at 16, to accommodatethe flaring spring-metal strip 17, which is bent circular and placed within the inner periphery of said annular fiange, and is held securely in its place by its own tension, and is prevented from accidental displacement by said incline or bevel to said fiange, and is pro vided with an inwardly-extending projection or tongue 18, which as the plate 11 is revolved IOO is designed to operate a portion of the locking device. Mounted over the end of the neck or stud 14, extending through the opposite side ofthe casing, is the opposite revolving operating and dial plate 1i), Which is designed to revolve over the frontinclosing cap 5 and is provided with an inwardly-extending annular flange 20, which is designed to snugly fit Within and revolve around the perforation 6, located centrally Withinsaid cap. The said annular flange is provided with a notch or opening 21, which when the various partsare operated is designed to be in alignment with the corresponding notch in the opposite revolving plate and in both the front and back plates of the lock-casing, said flange being also similarly inwardly inclined or beveled, as: at 22, which isdesigned to-acc'ommodate and retain in position the Haring springpiece 23, corresponding to that located Within the. annular flange of the opposite revolving plate, and is also provided within an inward- 24. The sai-d' front dial-plate is further provided With a series of degrees or graduations, which note the various combinations at which the1 look. isset, and is heldv securely in place over the top of said neck or stud 14 and upon the 'front of the lock-casing by means of the supplemental circular disk or plate 25, provided with` an integral stem 26, which is designed Ato be iitted Within said hollow neck or stud of the back plate and. be swaged or otherwise suitably rigidlysecured Within said stud, so that as` the back revolving plate rotates the said supplemental disk or plate 25, revolving over the face of the dial-plate, also revolves, and said supplemental disk, being provided with a pointer 27, indicates as it rotates thecombination at which the back revolving plate andthe parts of the lock which it operates are in their aligned and unlocked position. v

Loosely mounted upon the stud 14, extending through the barrel of the casing, is the locking-hook 28, which is provided with an upwardly-extending neck 29, at the upper terminal of which is an enlarged head 30, provided with a locking-tongue 31,v that is designed to engage the locking-shoulder i) ot' the link or hasp 8 and is always normally held in its locked position in engagement With said hasp by the tension of the leaf-spring 32 engaging the notch 33 at the lower end of the neck 29 and the notch 34 in the inclosing flange2, comprising the lock-casing. The said locking-hook 28 is further provided with the notch or recess 35, formed in one side of its outer periphery, and With the opposite annuflanges of the pvoted hook over which said.

tumblers are mounted is formed an annular recess or groove 39, Within which the inwardlyextending tongues 1S and 24 of the opposite operating-springs 23 and 17, respectively, are designed to travel and operate-the said tumblers as the opposite revolving plates rotate by the said tongues or projections engaging the stops 40, extending inwardly from said encircling anges 3S across the path of travel of the operating-tongues. The said tu mblers are further provided With the registering notches or recesses 41, that are designed when in alignment to correspond and register With the corresponding notches or recesses 4, 7, 15, and 21, respectively, of the back and front plates and the revolving disks located thereon, and said tumblers are further provided With the supplemental notches 42that are adapted to be throwny in alignment with the notch 35 of the locking-hook 2S for the-purpose of holding the parts of the lock rigid While changing l 4=the combination. ly-exten'ding operating tongue or projection j In. order that the annular flanges of the revolving disks 1l and 19 may not interfere `With the revolving tumblers located on each side of the intermediate hook,interposed beari ing-plates 43 are secured to the front and 'back 1 plates, respectively, and are provided with registering perforations and notches and ex- `tend slightly Within the perforations in said plates, forming a flange or seat upon which l the bottom of the anges upon the revolving plates rest and revolve therearound.

A spring-actuatedA locking-paWl 45 is provided with a longitudinal slot 46, Within which .the neck 29 of the locking-hook 28 projects and Works, as does, also, the spring 32, actuating said hook. The inner end or ends of said locking-pawl are adapted to be supported in and Work Within the recess 47, located in the side of the lock-casing, and the opposite end of said pawl beyond the end of the slot,v

against which the neck of the locking-hook is normally pressed is provided with a beveled bearing surface or face 48, which is designed to be normally borne against the inner end ot' the hasp or link 8 by the tension of the leafspring 49, one end'of which is secured within the notch 50, located in the bottom of the lockcasing and passing around the tumblers and body of the locking-hook. The opposite end is bifurcated and engages the notches 50, formed on the under sides of said paw] on opposite sides of the slot 46 therein. At the outer terminal ofisaid locking-pawl on either 'side ot the neck of the locking-hook projecting therethrough the same is provided with the inwardly-proj ecting locking-lugs51,Which are designed when the hasp is being unlocked to engage the several aligned notches or recesses. It can now be readily seen how the said lock is operated. Being in its locked position, the spring-pressed pawl bears firmly up upon the hasp andV keeps the same in engagement with the normally-locked lockinghook engaging said hasp, While the tumblers heilig in positions in Whichl their notches are IIO out of alignment prevents the said pawl from being pressed downward by bearing upon the hasp, and in this locked position the inwardlyextending lugs uponthe outer end of said locking-pawl are seated out ot' the circle of travel of the revolving tumblers within the guide and retaining notches or recesses 4 and 7 in the front and back plates, respectively. The front graduated disk 19 is first turned around once in orderthat the operating-tongue 24 of the spring 28, carried thereby, may engage the stop 40 of the vrevolving tumbler thereunder, and is now turned at a point where the figures thereon indicate by the indicator 52 upon the front cap 5 that the notch 4l in said tumbler is directly beneath the locking-lugs l ot' said locking-pawl. The front revolving plate is now turned back to the point' which indicates that the notch 2l in the annular flangeV is in alignment with the notch of the tumbler. The parts of the lock on this side of the locking-hook are now in position for unlocking. The front revolving dial-plate is now held firmly while the opposite revolving plate is rotated. This plate is turned, after being once revolved, so that the operating-tongue 18 ot' the spring 17 engages thestop of the tumbler thereunder until the pointer 27 upon the supplemental disk 25, carried by said revolving plate, indicates by pointing to the right number the point at which the notch within the tumbler is in alignment with the notch in the opposite tumbler and the opposite revolving plate. The said revolving plateis now turned backward, thus leaving the tumbler carried thereby stationary until it is indicated by the front supplemental disk that the notch l5 in the flange 13 is in alignment with the other aligned notches. The hasp is now pressed inwardly, which causes the spring-actuated lockingpawl to be depressed and throw the lugs 5l thereon in engagement with the aligned notches, thus connecting all parts together, so that by now turning either one of the revolving plates the locking-pawl is slid back within the recess 47, within which its inner ends work, and thereby carry the locking-hook 28 away from and out of engagement with the lockingfshoulder of the hasp, which can now be readily withdrawn. After the withdrawal of the hasp a slight turning of either of the revolving plates will throw all parts into their normal positions, except the revolving tumblers, which may be thrown out of alignment by turning said plates back and forth, the hasp being easily relocked by simply pressing the same within the casing, as can be readily seen.

A variety of combinations in the above-described loek maybe used, and for the purpose ot' changing the combination Whenever desired we provide the lock with a securing device i'or holding the tumblers and hook in their aligned positions while changing the combination. Secured to the inner periphery of the flange 2, inclosing the various parts of the lock, is the leaf-spring 52, riveted at 53 near the bottom of said casin g and, extending the requisite distance along the same, terminates in a right angular hook or tongue 54, and is further provided with an operatingbutton 55, secured .to the upper end of said spring and projecting through Yand without the perforation 56, located in the side of the lock-casing. When the main notches of the revolving tumblers and plates are in alignment with each other, the supplemental notches 42 of the revolving tumblers Vand the notch 35 of the hook are also aligned when the spring-actuated pawl is pressed inwardly and the said hook backwardly out of engagement with the hasp in the manner above described and in this position are designed to be engaged by the locking tongue or hook 54 by pressing the operating-button 55 inwardly. Holding the revolving tumblers and lockinghook in this position, the said revolving plates are turned separately and independently, which will cause the springs carried thereby to shift their positions within the annular flanges of said plates until the desired combination is made at which the tumblers will be thrown in alignment with each other, the point at which the notches in the flanges of the revolvin g plates are in alignment with each being always, preferably, zero.

The construction and operation of our permutation-padlock are now thought to be apparent without further description.
